To'nll whom it may roneern:

Be it. known that I, Oirmau. fisn'rox, a vitizen of the United States, residing at Lawrence, county of Essex. State of Massziehw sett-s, have invented an Improvement in Mechines for Making and Driving Staples, of which the following description, in connection with the aecompanyin" drawings, is it specification, like letters on the drawings representing like. parts.

This invention has for its object. the productionof a novel machine for making staples and driving them into leather, for boot and shoe work, or into other material for other urposes.

In t 10 machine herein shown as embodying my invention, the wire, referably somewhat flattened-to form it mto a ribbon, is taken from a reelby suitable feeding mechanism, herein shown as a pair of wheels, and is fed to the staple forming means, being bent thereby to form a staple which is then driven into the stock. The work is laced u 101] a yielding stock support which is selfaa a ting to the varying thickness of the stoc and which is eriodieally depressed to allow the stock to be fed, as is common in machines for inserting metallic fastenings.

The wire feeding mechanism is mounted upon a sliding carriage connected with the stock su port and controlled as to its position with relation to the staple forming means by the )osition of said stock support.. In operation t is carriage and wire feeding mechanism are moved away from the staple forming means. durin the lowering of the stock support for feeding the work and are returned towards the staple forming means as the stock support rises to clamp and cali-' per the stock. During the time when the stock support is descending and the carriage with itswire feeding 'mechanism is being moved away from the'staple forming means, as well as while the carriage with its feeding mechanism is approaching the staple forming means, andthe stock support is rising to clamp and caliper the stoe the wire feeding mechanism-is inoperative, i. e. it is disengaged'from the wire.

When the stock su port has risen to clamp and eali er the stoe a feed varying stop, mounte loosel' on the shaft to which is connected the main feeding wheel of the wire feeding nheehanism, is arrested in a position over-running of the feeding stroke due to rapid motions of the machine, I have provided means to lock the feedinp mechanism and thereby all liability of variation in length of staple which would oeeurfrom an overthrow of the feeding mechanism is avoided.

!. I prefer that the staple mode sha'i be formed with its ioints centered, and to. this end the wire is ent or oll'set laterally just before it is severed, so.tlmt in cutting it diagonally both points refined by the cut, that. is, both the point on t 10 severed blank and the point left on the body of the wire, shall be in the center of the width of the wire. To efl'eet this bending or offsetting of the wire I have provided a lip to support one edge of the wire near the point where it is to be sevsetting the wire and holding it while the cutters act to sever the wire into staple lengths.

The auxiliary bender, hereinbefore referred to, has combined with it means whereb its stroke may be varied nccordin to the size or width of the wire, the size 0 the lip and the extent of the bend desired.

The machine has suit-able means for acting against. the edge of the sole in which the staples are being-driven or the stock, whatever it may be, to feed the same overthe work support. 4.

The framework consists essentially of a head A of suitable shape to form bearin for the working parts to be described, said lead bein sustained on a column A su ported by suitable feet A". The top of thishead has erected u on it a suitable stand A containing a stu upon which is mounted a driver lever e, actuated by a suitable spring e, the force of which may be adjusted in usual manner. The end of. the driver lever e receives in it the upper end of a loose pin. a which is properly seat-ed upon the upper en of the driver-bar a actuated in usual manner by a lum or projection a, connected with a. suitab e disk A mounted upon the end of the main driving shaft A. The driver-bar has a driver it connected therewith by a screw h This driving shaft has fixed upon it a brake wlreel C with which cooperates a suitable brake B eoncaved at its face to embrace and act'upon the edge of the said wheel.

The brake is shown as mounted loosely on a too 15 of a sleeve B" clamped in suitable manner as by a clamp screw 2, see Figs. 1 and 2, on the hub of a lever 13 mounted on a stud B see dotted lines extended from the head, said lever having a projection it", one and of which engages loosely a slide rod (1, having at its upper end a wedge C which is employed to move the loose pulley 15" toward the fast pulley B on the s ml't A" whenever it is desired to start the machine. The rod C is extended to a starting treadle C to be described.

Between the brake wheel and the head of the machine is a lever C suita-iljv i eted at one end, as at C, see Fig. 24, on i re head A, and having a roller or other stud 26 which enters a cam groove 27 in the face of the brake wheel C. Said lever is slotted at its forming part of Fig. 28 a detail the knee IJO ' taincd by the column A,

shalt.

end and has adjustably connected with it a red C forming part of a connection between said lever and the stock support, to be described, so that when said rod is raised said stock support will be lowered or depressed.

The parts so far described and referred to by letters are found substantially in United States Patent No. 490,624, dated January 24, 1893.

The stock support 1), shown as a loosely revolving part carried by a 5 indie b, fitted to slide up and down in a ho low ost A susthe rod connected with said spindle and joined to a suitable lever C, the spring I), see Fig. 3D, surrounding said rod, the rod d" connected with the opposite end of said lever and toothed at its upper end as at d to be engaged by a suitab 0 device d mounted on a earriaqe d free to be moved in suitable guidewavs and attached to said rod C"; the treadle C jointed at its rear end to the rod C"; the arm 33 connected with the spindle b, and the rod3l attached to said arm, are and may be substantially as shown in United States Patent No. 383,455, dated May 29, 1888, with the exception of changes in shape which are immaterial.

The stock feeding wheel 111 about a vertical stud in an a m containing a shaft m provi ed at its front end with suitable bevel teeth, not shown, to engage teeth at the underside of the wheel m, said shalt having a suitable toothed sleeve m" loose thereon and carrying a pawl m, which engages a ratchet wheel at fast on the shaft m to rotate it intermittingly, and the s )rinp pres ed plug a", are substantially asin nited States Patent No. 403,835, dated May 21,1889.

The sleeve 111, see Fig. 2, of the stock teeding mechanism, is engaged by a toothed segment 10 on a lever l2 extended, see Figs. .5 and .23, from a sleeve hub 13, free to be turned about a suitable stud 1-1, held in cars 15 attached to the head A, said sleeve having a second arm 16 slotted. see Fig. 23, to thereby enable a link 17 to he adjustably connected therewith. Said link is in turn attached to a lever 18, pivoted on a suitable stud 1!), sustained by the having a roller'qr otherstud 20, which enters a cam groove 21 in a cam 22 fast on the main Said cam and the parts just described artnat the stock Feeling mechanism at the proper time, the length of the feed stroke being varied by adjusting the link I? inthe slot 23 of the lever 16.

The machine herein shown is adapted to be stopped with the stock support in its dc ivoted to turn C{'ustable block pressed position, and to insure this the arm It. Fig. 24, extended upwardly from the sleeve Pr has attached to it a roller or other stud B against which acts a cam B having a depression,

head, said lever see-left handof Fig. 24, in

which the roller may enter whenever, after the operator has removed his font from the starting treadle C. said depression arrives opposite said roller. a spring 34 snrroundim the rod C normally acting to depress said rod when the depression in the cam B permits it, and at the same instant the-brake...

shoe B is thrust against the brake wheel C, substantially as pr-i-vided for in said United States Patent No. 4i*U,62-1,befor-e rcferred to. it will be understood that the machine will be stopped amm'natieally whenever the foot of the operator is remove-d from the treadle C but the machine can stop only at a. certa n defined point with l'tilalifill to the position oi he shaft A and its cams.

The framework has a fixed thereon. s4:- Fig. '20. on which is mounted a carriage (1" adapted to be moved to and fro on said guide-rods r1 a link 51 connected at one end by a pin 52, see Fig. 2, with a lug b rising from a hub i1", see also Fig. 27, forming part of the carriage. The opposite end of the link 51 is jointed bv a pin 50 to an arm 11 mounted to turn on a F 0d 0, see- Figs. 1 and 18. The sleeve 0 has an arm a with which is jointed at 0 the rod 31 connect-ed with the arm 33 extended from the spindle b of the horn or stock support I).

The depression of the stock support to permit the feeding of the stock, causes the carriage to be mowed away from the usual driver h, the rising of the stock sup ort'to clamp and caliper the stock causing tiie carriage to be moved toward the driver.

The wire feeding mechanism is herein shown as comprising a. main feed wheel a" and a wheel I), which are mounted on the carriage a". The wheel a" which contacts with that side of the wire which is to form the outer side of the staple is substantially smooth at its periphery, so that it will not mar the staple forming material, This wheel is suitably .lseved on a fee-d shaft 0"", having fixed to it y a set screw (1", see Figs. 19 and 20, the hub of a partial geam" having a stop a. At one side 05 said gear a. said shaft, as shown herein, serves as a pivot for a second partial gear is having attached to it b a set screw a stop a" whic is extended laterally that it may meet and arrest the sto 1: carried by the feed shaft as said shaft is turnedbackwardly or in the direction of tits-e arrow Fi 18, toward the feed varying Ste? a".

The feed wheel 5, having precsrably a serrated face, as represented in 3, to act upon that part of the wire wh ch is to form the interior of the staple, is IDQ-Z'ittffldOOStEl)? upon a stud b, the inner end of which 15 fitted into a bore of a. tcver b freely about a. stud 6' see extended through a hub a, see Figs. 18 and 27, and held fixe of a rocking sleeve 0" two guide rods a" and a feed varying therein by a nut t". The feed wheel 7) is secured to a pinion b which is enga ed by a larger toothed gear 6' fast on the siheft 21" carrying the feed wheel a". The teeth of the pinion 5' and ear b are of such length that the pinion an gear are always in mosh even when ihe feed whc'els have been separated to release the wire.

The stud b receives about it one end of a strong spiral spring I), the opposite end of which is connected with an adjusting rod 5;" held in an ear I)" of the carriage a The free end of the lever b is split, as shown, and provided as herein represented with a hole to receive an ad'ustable abutment 3), shown as a steel bloc screwed into said lever and held in position by a suitable clampin screw I1 inserted through the split end of the lever.

Any indentations made at the inner side of the staple by the serrated face of the wheel 6' are closed up by the inward bending of the vrire in forming the staple, and the smooth-surfacedwheel (1? leaves the outer side of the staple smooth.

The csriage a has suitable holes 3, 4, see Fig. 21. The hole 3 rece ves the guide. rod a", while ,the hole 4 receives the guide rod a, and the carriage has n. artial sleeve a which receives arod a, which is referred to in the clsims as a positioning device The guidt rod a has at one end a tapped hole to receive a screw a, see Fig 20. extended through a hole in one end 0 a coupling bar a", thus connecting said bar rigidly to thestationary rod a. The opposite end of the coupling bar a receives the rod a, which is fixed therein by a set-screw o, the adjustment of said rod in said bar enabling staples to be made having le s of exactly the same length, or differing in length, as may he desired.

The stationary rod (1 has a connected rack bar a" which engages the teeth of the partial gear a having the feed varying smp a, and as the carriage is moved toward the staple forming means the horn then rising to clamp and caliper the stock, the teeth of said gear a in engagementwilh said rsrk turn the said gear, and putsnid stop in a variable position dc cndizw on the il1ltlilN':-S of the stock being c am )er The iced shalt which supports oer-pf the feed wire wheels curries also the gear 0 having the stop a", as heretofore dcscril d. and the teeth of said gear are engaged by the rack teeth a." of a feed mechanism actuator D which is shown separately in Fig. 20 and in relative position in- Figs. 2, l0, l8 and :0. The actuator is moved downwardly, to rotate the feed wheels forwardly to feed the wire, by it link I) jointed to said actuat r. at D, ssid link being in,turn jointed at D- see big. 18 to an arm 1) extended from a rocking sleeve D mounted on a stud D ssid sleeve having a second arm I) provided with n'roll I) see Fig. .25 which enters a cam groove cut in the inner end of a cam D fast on the shaft A. The cam groove for movin; the said actuator D, see Fig. 25, is cut to present at narrow lot-kin" space 100 and a \Vlt or part 101, see dotted ines. The outer wall I) of said cam acts to depress the actuator always for a like distance to thereb rotate the iced wheels forwardly to a de ed msition, and this defined position having won reached, the mechanism .for nctuatin said feed wheels is locked by the entrance therollerD in the narrow space 100, to posi tively terminate the forward movement of the feeding mechanism so that it is impossible for the feeding movement to overrun. Such overrunning frequently occurs in all wire feeding c ontrivances wherein the feeding movement is derived from a pawl having a stroke more or less of which is ell'ective in feeding, and by locking the actuator for the wire feeding mechanism it becomes possible to make staples accurately when the ms.- chine is running; at high speed.

The length of the backward movement of the feeding mechanism ctmtrols the length of wire next to be {ed and the backward movement of the feeding mechanism varies, according to the extent of upward movement of the actuator as will now be described.

The mechanism for moving the actuator D u wardly is as follows :-'lhe stud 1) receives aliout it near one end a suitable s ring D" which is fixed at one end with relation to the head A, the o ipositc end of the spring acting against a pin l) extended. from the arm D]. Said spring acts nornmlly to elevate the act-u: ator D into its starting position and turn the feeding mechanism, then released from the wire, backwnrdly until the stop a. meets the feed vmying stop a". The spring l) also acts normally to more the roll D toward the exterior cam wail D which defines the extent offeeding throw of the lever D and D, said roll not, however, touching the entire length of said cam wall D unless the lever D" is to be operated to feed the. who i or the formation of a staple of the maximum length which the machine is capable of making. the movement of said roll l)- lownrd the well I) being determined at all other times by the contact of the moving stop a on the gear a with the feed varying stop (1",tho position of which is controlled by the positioning device a above dr-scl'ibcd, the roll I) being thus stopped more or loss near the said well D in accord..-mce with the length of staple to be made.

lt will be understood that the shaft of and the feed wheels do not rotate continuously in one direction, but are rotntedintcrmittingly back and forth, and that the wire is fed only in the forward stroke of said feeding mechanism, said mechanism when turned lnrckwardly being inoperative and moving over the slationary wire. The upward m vement of the actuator under the action of the spring l)"' and consct uently the backward movement of the feeding mechani m is arrested whenever the stop a meets the. feed varying stop a", and the feeding mechanism is imnu-diately aftcntards closed upon the wire by the spring l1', which is permitted by n-.e.-|ns hereinafter described to move the feeding mechanism into operative position or to engage the wire.

The distance from the staple forming means at which the feeding mechanism engages the wire varies ..C(.0l(lil]f to the thickness of the stock, and the thickness of the stock determines the position of the stop a", which is turned more or less by its engagement with the stationary positioning device rd", as the carriage is moved away from the staple forming means. The roll D is arrested from moving far enough to contact with the wall 1) in the wider part 101 of the cam track, so that at the next stroke of the actuator the feeding mechanism will feed the wire only the distance required by the thickness of the stock.

The stud b has applied to it a suitable collar b, see Fig. 1], which formsan abutment for the rear side of the shank of the wire guide 6, shown best in Figs. 2 and 10, said guide receiving the wire w supplied by any usual or suitable reel.

The front. face of the carriage a is grooved, see Fig. 27, to form a guideway b", one side of which has a suitable gib b", said guideway receiving and said gib overlapping one end of the cutter carrier or knife holder 1)".

. The knife holder, represented detached in Fig. '26, consists essentially of a block having at its rear side a projection or shoulder c, see ig. 20, to enter a space behind the gib b", a shoulder c overlapping the edge e of the carriage. Said block has attached to it by screws c, shown by dotted lines Fig. 26, a gib c, which enters an auxiliary guideway c in the carriage a". This block is further provided with a threaded hole which receives a set screw passed through a hole in a. clamp c, said clamp acting upon one edge of a bender 0, herein re 'n'esented as set into a groove in the shank of a cutter c'. The

- bender is beveled at its inner edge 103, see

Fig. and the cutter is represented as having a projection t see Fig. 26 which enters a longitudinal vertical groove in an adjustable "at a, convcxcd at its rear side and resting in a concavityin the holder 11". The convcxcd back of the seat 11 has a tongue 54 cxtended transversely thereof which enters a groove cut in the concaved faceof the holder b". This tongue prevents any longitudinal movement of the seat on the. holder as the seat is being adjwcd in said holder. The hole iii the seat I: through which is extended the chi mp screw 0 is of larger bore than the diameter of said screw, and the underside of the head of the-screw, see Fig. 26', is c0ne shaped, and enters a conical seat in the can 1:,so tlnn said screw may not properly in any adjusted position of the scat. To adjust the seat, I have provided it with two holes which receive each an adjusti screw as 55, 56, and by turning out one iii said screws and turning in the otl1;1,.l1e seat maybe tipped as may be desired to adjust the acting edges of the cutters. The lower end of the movable cutter c has a step 0, see Figs. 5" and 5", in line with the cutting edge 0" against which acts the offset ear or shoulder of the bender, said shoulder cooperating with said stop to always position the lower end of the bender accurately with relation tetheacting edge of the movable cutter.

The clam screw 0 confines the cutter and bender firm y in place by one operation. The cutter and bender may be adjusted vertically in order to insure for them just the exact or proper working position, and they may also e adjusted to provide for any shortening of the cutter due to wear in grinding. The holder also has a longitudinal bore, which receives in it the shank of a connecting piece (i provided at its 11 per end with a head having a notch d whic receives a lip (1, Figs. 2 and 10, preferably of hardened steel and carried by one arm of a rocking lever d", mounted upon a stud 40 extended from the head,

said rocking lever having at its upper end a roller or other stud 41, which enters a eripheral cam groove 42 in a cam d, fixe to the main shaft. The connecting piece d is united to the holder by means of a-suitable set screw 44.

The cam d" acts through the lever d and the connecting piece (1 to reciprocate the holder 1: and actuates the movable cutter c of the wire cutting mechanism and the main member 0 of the bending mechanism.

The stationary wire cutter d Figs. 27 and 28 is clamped between a block d" and a cap d" bv means of a. set screw d". The block :1" has a holed", which receives a set screw (2", see Fig. 10, said set screw'entering a hole d in the carriage a", projections as d", see Fig. 27', at the rear side of said block entering a guideway d in said carriage, said guidcway being substantially at right angles to the guideway b" hercinbefore referred to.

The block (1" has a threaded h ole (1" see Fig. 28 to receive a screw d, see Fig. 3, said screw being extended through a cover plate if having at its underside a shoulder 10', see Figs. 7, 8 and 29, that in raeticc is l0-' cated near the edge 120 of a p ate e to thus constitute a groove to rcrcive and guide the wire. The plates (2 and constituting the cover plate are united by registering pins e on one plate cntering holes e on the other plate and holes 0 of the block (1".

The 120 shown as placed piece of wire forming the.

plate e is notched, as at e, and is of sufficient size to receive not c but also the acting end of the wire cut ter c.

Via-sing Fig. 29, it will be noticed that the member e of the cover plate has at or near one end a li e, and that the edge of said member bac of said lip nstitutes one wall of the groove for guiding the wire, the opposite well being formed by the shoulder w.

Viewing now Fig. 6, where the wire is in said groove, it will be noticed that the wire rests against the lip referred to, leaving a 5 nice back of said li with which the edge of the wire acting against said lip does not contact.

The bender c is located with relation to the groove in the cover plate as best represented in Fig. 5, and when said bender descenrL its beveled edge 103 acts upon the side of the wire op osite that at which it is supported by the lip referred to and at a pomt behind said lip, bending said wire laterally or offsetting it in the direction of its width. as best represented in Fig. 7, and thereafter in the further descent of the holder la", carrying the bender, the movable cutter member 0" also carried by said holder 6" meets the bent wire and cuts it on the full line represented in Fig. 8, leaving a notched end, the cut so made-,-it being supposed that a staple has been already cut from the wire-. completing the second point for the stap e next to be driverr leaving the body of the wire with its end winted to constitute the oint of one lo 0' the next staple to be lllfi fi.

lhe cutter holder b receives a short shaft d provided at its exterior, see Fig. 31, with a worm toothed gear (1', and at its outer end, see also Fig. 26, with an eccentric projection of.

The worm toothed gear is engaged by the teeth cf a worm screw d mounted in said holder. see Fig. 26, said worm screw having its exposed end slotted, as herein shown, for the reception of a. screw driver by which to rotate the worm screw to adjust the eccentric pmjection d into the desired position, a suitable set screw 1Z holding the shaft and its eccentric projection in ad usted osition.

have combined with the bloc d an auxiliary bender j, which is represented in Figs. 3. 4 and 10, as composed of a piece of thin steel pivoted atf' and having a projection, nrrched atf, to embrace the are, the upper eztlof said auxiliary bender having a cam slot)" in which is entered the eccentric projection d hereinbefore referred to, said eccentric projection working. in said slot. during the descent of the holder 6" causing said anxiliary bender to be turned about its ivot f, so that the said bender acting on t e edge of the wire at a short distance from bender c3 "I'd the lip e bends said only the end of the bender the holder 6" wire over said lip as a fulcrum, and by adjusting said eccentric projection variations in degree of the offset in the wire, see Fig. 7, preparatory to cutting the same in the diagonal line shown at 15), Fig. 8, The auxiliary bender therefore enables the wire to be olfset or bent )reparatory to cut-- ting off a portion thcrcoi to be bent into a staple, the direction of out being such a to insure a central position for the pointsd the sta les, leaving the pointed legs substantia y alike. v I
